Because of the “dysmorphic” phenotype from a homozygous genotype, these mutant genes would be highly unlikely to become fixed in a population.
The interpretation of the results as showing “latent” genetic capabilities has teleological overtones that are compatible with intelligent design.
There are various types of flagella, but all function like a rotary engine made by humans. Even non-ID scientists marvel at the complexity of these machines.
Let me tell a little story about blood clotting, Russell Doolittle, and Michael Ruse.
As Seth W. Cheetham and his co-authors put it, biology suffers from “demotivation into exploring pseudogene function by the a priori assumption that they are functionless.”
